Okay, I got Rascal in late October of last year when he was six weeks old. I figured he was born sometime in September. I am trying to figure this out because I need to buy him adult cat food now. He is ten months old. So when do I start giving him adult forumla I have kitten food and I think it will last until then. I feed him Iams and Eukanuba brands. I've also been feeding him Whiskas in a Pouch and Nine Lives(he loves those! Comes to me everytime I open one) I also have Iams canned food, but he dosen't like them. He prefers Whiskas so I am going to donate the rest of the cans rather then have them go to waste. I give him wet food once everyday and eats dry food all day long.
